Hypersomnia is one of the most consulted symptoms among patients evaluated at sleep disorder centers and it is frequently related to obstructive sleep apnea syndrome (OSAS). Our hypothesis is that Epworth sleepiness scale (ESS) is the parameter with the greatest predictive value in the OSAS diagnosis. We compared patients with OSAS diagnosis to a control group. In both groups we compared ESS with body mass index (BMI), neck circumference (NC), waist perimeter (WP). Anthropometric index (BMI, NC and WC), were similar in both groups (p < 0.10). When we analyzed ESS, a score greater than 10 was observed in the OSAS group, with a significant difference between groups (p < 0.001). Epworth sleepiness scale yielded 60% of sensibility, 82% of specificity and a positive predictive value of 85%. The negative predictive value was 52%. Confidence index was 70%. The relationship between OSAS and ESS scale was significant (Pearson Chi-Square value 7.5). Odds Ratio for apneas was 15 and its confidence interval was lower than 1.5 and upper than 141. We conclude that with ESS score exceeding 10 points OSAS should be suspected.
嗜睡症是在睡眠障碍中心接受评估的患者中最常被咨询的症状之一，且它经常与阻塞性睡眠呼吸暂停综合征（OSAS）相关。我们的假设是，爱泼沃斯思睡量表（ESS）是OSAS诊断中具有最大预测价值的参数。我们将被诊断为OSAS的患者与一个对照组进行了比较。在两组中，我们将ESS与体重指数（BMI）、颈围（NC）、腰围（WP）进行了比较。人体测量指标（BMI、NC和WC）在两组中相似（p < 0.10）。当我们分析ESS时，在OSAS组中观察到得分大于10分，两组之间存在显著差异（p < 0.001）。爱泼沃斯思睡量表的敏感性为60%，特异性为82%，阳性预测值为85%。阴性预测值为52%。置信指数为70%。OSAS与ESS量表之间的关系显著（皮尔逊卡方值为7.5）。呼吸暂停的优势比为15，其置信区间低于1.5且高于141。我们得出结论，当ESS评分超过10分时，应怀疑患有OSAS。
